NOTE: This has been floating around in a different form as a mussar schmooz. My father reworked it into a joke of sorts, thought the kernel of mussar remains.
A charedi man and a chiloni woman were sitting near each other on a bus. The charedi fellow offers her an apple. She asks, biting into the apple, what prompted the gesture. He replies, “Well, after Eve bit from the apple, she realized she was naked.”
She smiles and offers him a bite. Accepting the offer, he asks why she decided to return the favor. “Because,” she responds, “after Adam ate from the apple, he had to go to work!”
